Coastal Crabs

An interactive guide to the common coastal crabs of New Zealand.

Crabs are an exciting and diverse group of invertebrates found around our coastline - in the shallow intertidal zone, at snorkelling and diving depths, and down in the deepest trenches and abyssal plains of our oceans.

Now you can identify them in the field with Coastal Crabs - a guide to the crabs of New Zealand, a fully illustrated interactive pdf with high-quality images of the animals in life. Just click on an image in the morphology index and you will be taken to a species page packed with information, beautiful images, and icons to simplify identification.

New species are added as they are available, so divers, please send us your images to be considered for up and coming versions.
